T 0 all whom 'it may concern:

Be it known that I, 'WILLIAM MURPHY, a

citizen of the United States, residing at Buffalo, inthe county of Erie and State of' ltain stages of the operation of the machine.'

This 'particular device is shown as a plied tothe style ofmachine set Lforth inA atent No. 580,378 to 4Joseph P. Cleal andFrank A. Reinhard, dated'April 13, 1897, although from a consideration of the nature of these improvementsitwill be obvious to those skilledin the art that these devices may be applied to various other types of machines, With these and incidental objects in view,

the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are lset forthin appended claims anda preferred form of embodiment of which is hereinafter pecically described with reference tothe segments 11l which llare suita awings which accompany and form. 'part of this s eciiication.

. Of said drawings: Figure 1 represents an` end elevation of the machine to which these improvements have been ap lied. Fig. 2 represents an enlarged detai view of the feeding mechanism for the detail strip, showi inghfhe printing carriage in raised position,A

the general operation of this character of machine which is at present well known in theart, the keys 10 are der lressed to repase and upon j. the operation of a crank andle (not shown herein but shown in the aforesaid patent),

resent the amount of the nrc so that theyvassurne positions corresponding to the values of the keys depressed. The 'y revolution of the mainoperating handle/of. fthe; machine imparts at :each operationof:

'then fed over the "the win the machine a complete revolution to the the operating shaft 12 to which shaft is made fast a disk 13 in Whichdisk` is formed a cam rooge 14 as shown in dotted lines in Fig. 1 into'which groove projects a pin 15 fast upon theupper end of a paper carria e 16. It will be noted that the shape o the cam groove 14 is such that'the carriage 16 which slides between vsuitable guide pieces 17, will be reciprocated twice at each revolution o-fthe disk 13 and thereby at each operation of the machine, the rst reciprocation being' utilized for the rinti of a checkand the second for'printing on tie detail strip. The

check paper is` fed from a storage roll 1.8,

throng .a chute -19 and-thence between certain feed rollers which are operated by the main operating shaft -of the'machine to feed the paperoverfa platen roller 20 which is mounted .upon the aper. carriage 16', this roller being. mounted? in juxtaposition .to the printing 4@line of the type carriers 11 A suitable knife carried upon the carriage-16 serves to sever the checkto permit the same to be ejected from the machine by means of an ejector21 whichis suitably' operated from 'the shaft 12 at each operation of the machine. v v

Onl the lower rtionof the carriage'- 1 6 is mounted a det .s trippsupply roller v22 from which the detail stri 22 is unwound' and is aten 'roller 20 'and back to the windi ro er 2 3. The supply roller 22'is provide with a ratchet wheel 24 and roller 23 is supplied with -a similar rato et wheel 25, the `latter wheel being engaged by @spring-'pressed retaining Vpav'vl26. Y

Forv the purpose of'feeding the 'detail striplat-each operatlon'of themachin'e an arm 27 is provided which is pivoted upon the' same lshaft 28 with the Winding roller 23 (see Fig.

2), and this arm 27 carries-afeed pawl 29 which'engages the ratchet'wheel 25. oted .to the main frame of the machine at 30 is a link 3 1 which at its 'lowerend is formed roo with a slot '3 2 in which plays apina33 carried u on the middle'portion of .the -arr n .27. i It will-thus be apparent that when the carriage 16 is carried upward 'for rinting inthe manner previouslyv describe the shaft 28 carrying the arm27 is 'of course carried upward but the outer end of the arm 2'7 cannot be carriedupward because ofv the connection v Av vith,thes'tationary link 31 and' therefore the 11o I feed pawi 29 slips idly over the ratchet wheel 25,; until the carriage' IG-Q-retulns downward to lts normal position during which time the pawl 29 engages the ratchet 25 and feds the etail 4strip during thisreturn movement of thecarria e. ."As'stated above the carriage1 is given a ouble reeiprocation, but the intery mediate reciprocation is a slight one being merely for tie purpose of withdrawing the carriage from the type to permit the check to be ejected and then again forcing "the hammer against the type to print upon the detail 'link 31 is such'that the 'arm 27 will-not begin stance bein re to be operated by the 1ink-31during this short extentv of the intermediate reciproca-v tion of the carriage. This provision for the discontinuance'of the -feed during this reciprocation is an adjunct of theloclringr feature to be presently* described. The general constructlo'nho'wever of the parts heretofore set k forth is substantially the 'same as that cle-- scribed in the aforesaid patentand contained 'in machines now extensively ,marketed 4rThe particularffeature of; the present im? provernnt lwill now be described. Machines of this particular character are usually 'provided with a-device for preventing the 'issuance of a check, this device in thepresent inatedb'y a so-called ,"Onv and Off o '40 which when turned by the operator efife'ots the discontinuance of the feed of the `check ypaper so that no check is 1 issued u on that operation of the` machine; andas t e construction 'of this On and Off knob and its attendant arts is well known no further description oft e same will be given. When the check feed is discontinued' in auch manner, vthe 'carriage 16 is` nevertheless reciprocated twice at each oper ationof the machine and under ordinary circumstances of course simply causes both impressions to be taken upon Ithef detail strip ist ut since there is no feed of the detail strip during this time, the impressions would be taken one on to of the other since no check strip intervenes etween the ltype and the de- ,tail strip."` This h'as laid the machine open to manipulation by ermitting the operator, when the checkfee is thus discontinued, to advance the detail strip between the successive impressions and thereby print upon the detail strip a double record for a sin leV transaction, thus of course.l producing a f a se 'entry in the machine. To prevent such ma- .nipulationmeans have been providedfor reventing such advancement of the strip w le the platen is within the range of its operative effectiveness,` the particular means in the present case constltutin duplex pawls 50. and 51, which are pivote .at 52 to the lower portion of the carriage 16 between the two ratchet wheels 24 and'Z. The. up er ends i of these'pawls are normally force toward each other by means of aspring 53 compressed between the lower ends, and each pawl has upon its outer side a single tooth 54 larranged to .engage their respective ratchet wheels.` o Pivoted to the main frame at 55 is a link 56 the upper end of which carries a pin 57 ,which projects laterally through a f slot vformed in the carriage 16 and between the two pawls 50 and 51. The inner sides of these two pawls are so shaped that the pin 57 their respective ratchet wheels because of the lessening ofthe distance between the two pawls near their pivotal points so that the pin in going down between the pawls forces them apart inthe manner described. This condi-tion obtains while the platen rollerZO is' within its range of eifectiveness, that is while it is still in position again to be reciprocated to cause'the second impression to be taken, so that the locking of the ratchet wheels 24 and 25 by the pawls 50 and 51 absolutelyl prevents any feeding of the paper at this point. As soon howeveras the carriage has completed its printing movement andl has disengaged sufficiently to cause the arm 2,7 to

4begin the normal feed ofthe strip in the man-l ner previously described, the spreading pin 57 is at this' time in the widened portionbetween the two. pawls 5() and 51 so that the .pawls may .spring back to normal. position and release the ratchet wheels 24 and 25 t`o permit the Inormal feed of the strip.

Of course it might be sufficient in some cases to lock merely one of the detail stri rollers but it would si am preferable to locli both of them in orde to prevent manipula-A tion of any slack paper, and of course various modifications of the abr: ffe devices lmight well be used not only in this ype of machine but in others. Wh?? the form of meel .anism here shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not desired to confine the invention to the one form of embodiment herey disclosed, for it is susceptible of embodiment in various forms-all co,f ing within the scope of the claims which foliow.
